One way I could DRY up hunt_for_bugs and fix_bugs

gistfile1.rb

def hunt_for_bugs(score, location)
  bug_work(hidden_bugs(location), :hide_points).size
end

def fix_bugs(score, location)
  just_fixed = bug_work(found_bugs(location), :hit_points)
  @bug_list.reject! { |bug| bug.dead? }
  just_fixed.size
end

def bug_work(bugs, :attr)
  bugs.take_while do |bug|
    points = [bug.send(attr), score].min
    bug.send("#{attr}=".to_sym, bug.send(attr) - points)
    score -= points
    bug.send(attr) == 0
  end
end
